Along with Amanda, Darren, Liam and Gabriel, he is part of the small group of friends who discovered the Undernet when they were teenagers.

Recently, a leak occurred, people were able to access the Undernet and Gabriel needs his friends from that time to find a way to plug it before it's too late. So he will pay for their first class plane ticket and invite them to go to a 3-story hotel in Pennsylvania, which he has rented in its entirety to make it their headquarters. The hotel is located near the place where Gibson Lane, a 15-year-old, has just killed nearly 60 people in his neighborhood. Yoshi is a computer technician and his role is to install all the equipment they need and ensure that it works properly.

A few hours after their arrival, Yoshi, Liam, Darren and Amanda will surprise PH34R stabbing Gabriel in a room of the hotel. Darren will force her away from Gabriel by threatening her with his gun, but the latter was already seriously injured. Some of them want to kill PH34R but Gabriel asks them to let her go, because they will need her to put an end to all this. PH34R leaves, but Gabriel will die peacefully in Liam's arms shortly after. Gabriel will have time to tell them that he has just destroyed the Internet on the entire planet and that there is only one network left available to continue the fight: w0rldtr33.net.
